Catechism of the Catholic Church

1720 The New Testament uses several expressions to characterize the beatitude to which God calls man:

- the coming of the Kingdom of God; ¹⁶

- the vision of God: "Blessed are the pure in heart, for they shall see God" ¹⁷

- entering into the joy of the Lord; ¹⁸

- entering into God's rest: ¹⁹

There we shall rest and see, we shall see and love, we shall love and praise. Behold what will be at the end without end. For what other end do we have, if not to reach the kingdom which has no end? ²⁰

1721 God put us in the world to know, to love, and to serve him, and so to come to paradise. Beatitude makes us "partakers of the divine nature" and of eternal life. ²¹ With beatitude, man enters into the glory of Christ ²² and into the joy of the Trinitarian life.

1722 Such beatitude surpasses the understanding and powers of man. It comes from an entirely free gift of God: whence it is called supernatural, as is the grace that disposes man to enter into the divine joy.

"Blessed are the pure in heart, for they shall see God." It is true, because of the greatness and inexpressible glory of God, that "man shall not see me and live," for the Father cannot be grasped. But because of God's love and goodness toward us, and because he can do all things, he goes so far as to grant those who love him the privilege of seeing him.... For "what is impossible for men is possible for God." ²³

1723 The beatitude we are promised confronts us with decisive moral choices. It invites us to purify our hearts of bad instincts and to seek the love of God above all else. It teaches us that true happiness is not found in riches or well-being, in human fame or power, or in any human achievement - however beneficial it may be - such as science, technology, and art, or indeed in any creature, but in God alone, the source of every good and of all love:

All bow down before wealth. Wealth is that to which the multitude of men pay an instinctive homage. They measure happiness by wealth; and by wealth they measure respectability.... It is a homage resulting from a profound faith ... that with wealth he may do all things. Wealth is one idol of the day and notoriety is a second.... Notoriety, or the making of a noise in the world - it may be called "newspaper fame" - has come to be considered a great good in itself, and a ground of veneration. ²⁴

1724 The Decalogue, the Sermon on the Mount, and the apostolic catechesis describe for us the paths that lead to the Kingdom of heaven. Sustained by the grace of the Holy Spirit, we tread them, step by step, by everyday acts. By the working of the Word of Christ, we slowly bear fruit in the Church to the glory of God. ²⁵

1725 The Beatitudes take up and fulfill God's promises from Abraham on by ordering them to the Kingdom of heaven. They respond to the desire for happiness that God has placed in the human heart.

1726 The Beatitudes teach us the final end to which God calls us: the Kingdom, the vision of God, participation in the divine nature, eternal life, filiation, rest in God.

1727 The beatitude of eternal life is a gratuitous gift of God. It is supernatural, as is the grace that leads us there.

1728 The Beatitudes confront us with decisive choices concerning earthly goods; they purify our hearts in order to teach us to love God above all things.

1729 The beatitude of heaven sets the standards for discernment in the use of earthly goods in keeping with the law of God.
